New Car Idea, CAN IT WORK?

[irishkid200]

So I was researching something for class involving air as a fuel source. I then read up on multiple things and had an idea for a car. What if: You extracted the nitrogen from the air, made it into liquid nitrogen, and then used it to power a car using this: http://www.planetforward.org/media/tv-segments/can-liquid-nitrogen-be-used-to-fuel-cars. Don't mind this formatting, it's quite late at night and I'm too tired to care.

Nitrogen is not a fuel, it is just a way of storing the energy. And not a very efficient one apparently: https://en.wikipedia.org/wiki/Liquid_nitrogen_vehicle

irishkid200, your idea might be possible to implement but I suspect it would be severely expensive and unprofitable.

The rules require that enough of the discussion take place here so that it doesn't depend on outside links and/or videos. Can you explain how liquid nitrogen is used? i.e. is it a chemical reaction? Is it because it's liquid and there's energy being extracted from the phase change? That's something you should be explaining.

Phase change might work okay on other worlds where the pressure difference is greater. Probably won't be Nitrogen though.
